HelloPharmacist Scorecard of Enzyme Defense by Enzyme Science
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
Enzyme Defense contains 8 active ingredients. Protease and serratiopeptidase are digestive enzymes meant to help break down proteins.
L-lysine is an amino acid; it's studied mainly for cold sores. Vitamin D3 supports bone health and calcium absorption.
Nattokinase is an enzyme derived from fermented soy that's thought to support circulation. Catalase and mucolase are additional enzymes.
The product also contains one inactive ingredient: a vegetarian capsule.
Does it work?
Not established
The only ingredient here with established effectiveness is vitamin D3, which is effective for rickets, renal bone disease, low blood phosphate (familial hypophosphatemia), and low parathyroid hormone (hypoparathyroidism). L-lysine is possibly effective for cold sores.
The effectiveness of protease, serratiopeptidase, nattokinase, catalase, and mucolase is not established in the data we hold — evidence is either insufficient or not rated.
How safe is it?
Well-documented data
Protease is generally well tolerated but may cause digestive upset or allergic reactions; rarely, occupational exposure to airborne proteolytic enzymes has caused allergic rhinoconjunctivitis or asthma. L-lysine is generally well tolerated at typical doses, though high amounts may cause stomach upset, diarrhea, or abdominal pain.
Vitamin D3 is generally safe at recommended doses, but very high doses over time can cause toxicity with symptoms like high blood calcium (hypercalcemia). Nattokinase is generally tolerated short-term but has a blood-thinning effect, so caution applies to people at risk of bleeding.
One case of brain bleeding has been reported with nattokinase and aspirin together. For pregnancy and breastfeeding: protease should be avoided in pregnancy unless prescribed, and use is not recommended while breastfeeding.
L-lysine's safety in pregnancy is not well studied, and there isn't enough data on breastfeeding use. Vitamin D is often used in pregnancy at recommended amounts but only under doctor guidance.
Nattokinase should be avoided in pregnancy and while breastfeeding due to insufficient safety data.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist if you take blood thinners or antiplatelet drugs (like aspirin or warfarin) — nattokinase increases bleeding risk at Moderate severity. Also double-check if you're on blood pressure medications (antihypertensives), heart rhythm drugs (verapamil, diltiazem), digoxin, atorvastatin, thiazide diuretics, or any drugs your liver breaks down via CYP3A4 — vitamin D interacts with all of these.
No interactions are documented in our data for protease, serratiopeptidase, catalase, or mucolase, but we could not check the last three.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
Enzyme Defense is intended as a digestive support with enzymes and added nutrients, but it carries real interaction risks — especially with blood thinners, heart medications, and blood pressure drugs. If you take any prescription medication, especially anything for your heart, blood pressure, bleeding, or cholesterol, check your specific drugs against the tool on this page before starting.
Talk to your pharmacist or doctor first.

Enzyme Defense by Enzyme Science Drug Interactions
HelloPharmacist Interaction Report
Enzyme Defense by Enzyme Science contains several active ingredients, and some of them do interact with medications.
The most serious concern is nattokinase, which can increase bleeding risk when combined with blood thinners or antiplatelet drugs (anticoagulants/antiplatelets) — a Moderate severity interaction. There's also a case report of brain bleeding in someone who combined nattokinase with aspirin.
Read the full breakdown — every affected drug type, severity by severity
Vitamin D3 in this product interacts with multiple medication types at Moderate severity: thiazide diuretics (water pills for blood pressure), which together can raise calcium levels too high; heart rhythm drugs like verapamil and diltiazem, which vitamin D can weaken; the statin atorvastatin, which vitamin D may reduce; digoxin (a heart medication); and calcipotriene (a vitamin D-like topical psoriasis treatment). Vitamin D also has a Minor interaction with CYP3A4 substrates (a large group of drugs your liver breaks down).
L-lysine has one Minor interaction: it may reduce the effects of 5-HT4 agonists (medications used for certain gut problems). We couldn't check three other ingredients — serratiopeptidase, catalase, and mucolase — because we hold no interaction data for them.
Altogether, these interactions span 873 individual medications. Use the medication checker below to see if any of your drugs are affected.

For each ingredient in Enzyme Defense with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Vitamin D3
Aluminum
Vitamin D might increase aluminum absorption and toxicity, but this has only been reported in people with renal failure.
The protein that transports calcium across the intestinal wall can also bind and transport aluminum. This protein is stimulated by vitamin D, which may therefore increase aluminum absorption. This mechanism may contribute to increased aluminum levels and toxicity in people with renal failure, when they take vitamin D and aluminum-containing phosphate binders chronically.
Atorvastatin (Lipitor)
Vitamin D might reduce absorption of atorvastatin.
A small, low-quality clinical study shows that taking vitamin D reduces levels of atorvastatin and its active metabolites by up to 55%. However, while atorvastatin levels decreased, total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol levels did not substantially change. Atorvastatin is metabolized in the gut by CYP3A4 enzymes, and researchers theorized that vitamin D might induce CYP3A4, causing reduced levels of atorvastatin. However, this proposed mechanism was not specifically studied.
Calcipotriene (Dovonex)
Taking calcipotriene with vitamin D increases the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with vitamin D supplements might increase the risk of hypercalcemia.
Digoxin (Lanoxin)
Theoretically, hypercalcemia induced by high-dose vitamin D can increase the risk of arrhythmia from digoxin.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and digoxin concurrently.
Diltiazem (Cardizem, Others)
Theoretically, hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of diltiazem for arrhythmia.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically this could also occur with diltiazem. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and diltiazem concurrently.
Thiazide Diuretics
Theoretically, taking thiazide diuretics and high-dose vitamin D can increase the risk of hypercalcemia.
Thiazide diuretics decrease urinary calcium excretion, which could lead to hypercalcemia if vitamin D supplements are taken concurrently. This has been reported in people being treated with vitamin D for hypoparathyroidism, and also in elderly people with normal parathyroid function who were taking a thiazide, vitamin D, and calcium-containing antacids daily.
Verapamil (Calan, Others)
Hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of verapamil for arrhythmia.
Hypercalcemia due to high doses of vitamin D can reduce the effectiveness of verapamil in atrial fibrillation. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and verapamil concurrently.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Vitamin D might induce CYP3A4 enzymes and reduce the bioavailability of CYP3A4 substrates.
There is some concern that vitamin D might induce CYP3A4. In vitro research suggests that vitamin D induces CYP3A4 transcription. Additionally, observational research has found that increased UV light exposure and serum vitamin D levels are associated with decreased serum levels of CYP3A4 substrates such as tacrolimus and sirolimus, while no association between UV light exposure or vitamin D levels and levels of mycophenolic acid, a non-CYP3A4 substrate, was found. A small, low-quality clinical study shows that taking vitamin D reduces levels of the CYP3A4 substrate atorvastatin and its active metabolites by up to 55%; however, the clinical effects of atorvastatin were not reduced. While researchers theorized that vitamin D might induce CYP3A4, this proposed mechanism was not specifically studied.
Nattokinase
Anticoagulant/Antiplatelet Drugs
Nattokinase might increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
Nattokinase has thrombolytic and anticoagulant effects. There is a case report of intracranial hemorrhage in a patient who added nattokinase to aspirin therapy.
Antihypertensive Drugs
Theoretically, nattokinase might increase the risk of hypotension when used with antihypertensive drugs.
Some clinical research suggests that nattokinase may reduce systolic and diastolic blood pressure.
L-Lysine
5-Ht4 Agonists
Theoretically, lysine may reduce the effects of 5-HT4 agonists.
Animal research suggests that L-lysine is a partial serotonin receptor 4 (5-HT4) antagonist and inhibits diarrhea induced by the 5-HT4 agonist, 5-hydroxytryptophane.
